LOCK FOR FIREARMS.

SPECIFICATION forming part of Letters Patent No. 594,863, dated December7, 1897. Application filedJ'une 25, 1896. Serial No. 596,899. (Nomodel.)

To all whom, if; may concern;

Be it known that I, OTTO P. ELTERICH, a citizen of the United States ofAmerica, and a resident of New York, in the county and State of NewYork, have invented certain new and useful Improvements in Looks forFirearms, of which the following is a specification.

Myinvention has reference to improvements in firearms, and especially tothe locks of hammerless guns, it having for its objects, first,

to obtain simplicity of construction and durability, combined withabsolute safety, and, secondly, to enable the gun to be cooked withsafety in case the trigger-spring should break.

The nature of my invention will best be understood when described inconnection with the accompanying drawings, in which- Figure 1 representsa longitudinal central section of a lock embodying my invention appliedto a double-barrel hammerless shotgun. Fig. 2 is a similar view showingthe barrels open and the construction of the springhammer slightlymodified. Fig. 3 is a side elevation of the trigger-plate and partsthereto appertaining removed. Fig. 4 is a top View of the same. Fig. 5is a cross-section on the line 5 5, Fig. 1, taken through thegunbarrels. Figs. 6, 7, and S are detail views. Fig. 9 is a detail viewillustrating a modified form.

Similar letters and numerals of reference designate corresponding partsthroughout the several views of the drawings.

In the present example I have illustrated a double-barrel gun, with itsaccompanying mechanism, but shall describe the mechanism as if adaptedfor a single-barrel gun, since the operative parts are merelyduplicated.

Referring to the drawings, the letter A designates the frame of the gun,adapted to receive the trigger-plate B and its attached mechanism, saidtrigger-plate being secured to the frame by bolts 1 and 2, as usual. Thebarrels O and the fore-end D are attached to the frame A in the mannerusual in breakdown guns, the usual form of top lever E and an automaticsafety device 8 being provided.

According to my present invention I combine the hammer and mainspring toform what I shall term the spring-hammer II, which is made substantiallyin V form, with one leg shorter than the other. It is fitted into arecess formed in, the side of the triggerplate B and is secured by ascrew Z), passing through a horizontal extension of the shorter limb. Atits upper end the longer limb is provided with a head 0, adapted toengage with the firing-pin d, or, as shown in Fig. 2, it may be formedalso with a pin d, adapted to strike the cartridge. The spring-hammerisadapted to be engaged near its upper end by a pin 6, carried by thelifting-lever tumbler F, which is adapted to turn about a stud f,secured in upright lugs formed on the trigger-plate B. The lifting-levertumbler is provided with a vertical arm g, carrying the pin 0 beforementioned, a horizontal arm h, adapted to be engaged by the tappet i onthe lug G, attached to the gun-barrel, and a second horizontal arm j,provided with two notches adapted to be engaged by the sear m. The scaron is pivoted at Z to suitable lugs on the triggerplate B, and itsrearwardly-projecting arm I is provided with a horizontal pin n, adaptedto engage with a slot 0, formed in the web of the trigger '1. Thetrigger-web is also provided with a notch 23, into which extends the endof the trigger-spring q, the latter being secured by a screw 0", asusual.

I will now proceed to describe the operation of the parts, includingthose usually found in firearms of this description. The top lever E isfirst turned laterally, thereby drawing the bolt i from the recess t,formed in the lug c on the barrels O, thus permitting thebarrels to beturned down for the insertion of the cartridges. With the turning downof the barrels the tappet t' on the lug G engages with the arm h of thelifting-lever tumbler F and turns the same to the position shown in Fig.2, thereby throwing the spring-hammer II backward. The scar m is thenturned about its pintle by the action of the trigger-spring q,transmitted through the trigger, and its nose drops into the top notch011 the lifting-le-.

ver tumbler. The barrels are then turned upwardly again. hen the triggeris pressed, the sear m is lifted and frees the lifting-lever tumbler, asusual, and the springhammer descends with its full force.

The lock can be cooked with the aid of the fore-end by the introductionof a second cocking-lever w, as shown in Fig. 9, which engages the arm hof the lifting-lever tumbler and operates in connection with thefore-end in the usual manner.

In View of the pin-and-slot connection between the scar and trigger I amalso enabled to use the gun should the trigger-spring q break, it beingsimply necessary to turn the trigger forward while the gun is beingcocked, thereby elevating the engaging end of the sear and throwing thenose of the same in position to engage the top notch in the liftinglevertumbler F. After the gun is cooked the sear will hold the lifting-levertumbler with the greatest safety. It will also be noticed that the useof a special sear-spring is dispensed with, as the trigger-springfulfils the functions of the former.

It is of course to be understood that the lock herein described can beapplied to guns of other constructions and also to pistols.

What I claim as new is 1. A look for a firearm,comprisin g aspringhaminer,alifting-tumbler operated byamovement of the barrel andhaving an upright arm engaging with the spring-hammer, and a scarengaging said tumbler,substantially as specified.

2. A lock for a firearm, comprising a springhammer, a lifting-tumblerhaving an upright arm engaging with the hammer and an arm havingconnection with the barrel, whereby the tumbler is operated bya-movement of the barrel, and a sear engaging said tumbler,

substantially as specified.

3. A lock for firearms, a trigger-plate provided with means forsupporting the operative parts of the lock, said parts being composed ofa lifting-tumbler having rear notches,

whereby the tumbler is operated by a movement of the barrel, and anupright arm, a scar adapted to engage in the notches, a springpressedtrigger having a sliding connection with the sear, and a V-shapedspring-hammer engaged by the upright arm of the liftingtumbler,substantially as specified.

4. In a lock for firearms, a hammer and mainspring formed of one pieceand affixed to a trigger-plate, alifting-tumbler operated from thebarrel and having connection with the spring-hammer, a trigger having aslot, and a sear engaging the lifting-tumbler and having a pin extendedinto the slot in the trigger, substantially as specified.

5. In a lock for firearms, the combination of a trigger-plate, aspring-hammer made in one piece,a lifting-tumbler pivoted to thetrigger-plate and provided with an arm engaging the spring-hammer andwith a forwardly-extended arm, an operative connection between .thelatter arm and the barrel and a sear engaging the lifting-tumbler,substantially as specified.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 11th day of June, 1896.
